FASTENING DEVICE FOR ICE-CHESTS.

. Specification of Letters Patent.

Patented Feb. 11, 1913.

Application filed September 10, 1912. Serial No. 719,672;

To all whom it may concern:

7 Be it known that 1, ANDREW J. ALLISON, a citizen of the United States,residing at Hartshorne, in the county of Pittsburg and State ofOklahoma, have invented certain ures of reference marked thereon, whichform a part of this specification.

This invention relates to new and useful improvements in eccentriclatches forvthe doors of refrigerators, coolingrooms, windows or otherdoors requiring force to close and release the same and where anairtight joint is desired.

The invention comprises various details of construction and combinationsand arrangements of parts which will be hereinafter fully described,shown in the accompanying drawings and then specifically defined in theappended claims.

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a side elevation showing a door held in a locked relation bymeans of my invention. Fig. 2 is a view showing the latch in the act oftilting the keeper to allow the latch point to pass behind and againstthe door strip, a further lifting of the latch handle causing the doorto be locked, and Fig. 3 is a detail perspective view of the latch andstrip adapted to be attached to the door, the latch being designed totilt back to a vertical position after the latch has passed by saidcatch.

Reference now being had to the details of the drawings by letter,A-designates a door, a portion of which only is illustrated but which isadapted to be hinged in the usual manner, and C is a portion of a doorcasing. A cylindrical bearing member D is formed of a late which is bentupon itself, and has anges D which are fastened to the casing 1n such aposition that the bearing portion will be horlzontally disposed. Saidbearing portion is provided with an angular and inclined slot E.

A; locking bolt or latch is designated by letter F and is of cylindricalform and has latch;

in, said bearing member, said bolt or latch having an angled end F, thepurpose of a rotary and longitudinal movement withwhich will bepresently described. A handle H projects from said bolt orlatch throughthe angled slot E and serves as means for rocking the bolt andmovin'gthe same longitudinally when the shank portion of the handlecomes in, contact with the inclined edges of the slot. It will be:

noted on reference to the drawings that,

when the latch is in the-position shown in Fig. 1, it is in a lockedrelation and, when in theposition shown in the dotted lines in 1, willallow the door to be swung open. A plate K is fastened .to thedoor,'preferably near its free end, and to said plate s pivotallymounted upoh a pin N a keeper 0 which has a lug or" heel Q-projecting Ilaterally therefrom, aportion of which keeper is bent to form a liporfiange R. An upper portion of the kee er has an elongated slot K formedtherein, and a pin S fastened'to the door asses through said slot andserves as a guide to the keeper as it swings to its limit in oppositedirections. It will be noted that the pivotal .point of said keeper isat one side of the center of the latter for the purpose of throwing thegreater part of the weight to one side which will have a tendency toprevent the upper portion from falling back from over the The'operationof my invention is as follows r-VVhen the door isajar, the bolt or latchis adapted to assume the position shown in dotted lines in Fig. 1. Afterthe door is closed, the handle is swung to the position shown in Fig. 2of the drawings when the angled end F of the bolt will contact with theinclined flange R, causing the keeper 0 to tilt to the position-shown indotted lines in Fig. 1 and allow said angled .end to pass behindthekeeper O and afur ther upward throw of the lever to the positionshown in solid lines in Fig. 1 will cause the angled edge of the bolt tocontactwith the projection Qand tilt the keeper 0 to an uprightposition, as shown in solid lines in Fig. 1 of the drawings, thussecurely looking the door. A reverse downward movement of the handlewill cause the angled end of said bolt to swing outwardly and contactwith the inner face of the keeper 0 and im part the initial startingmovement to the opening of the door, this being accomplished while thelatch is rocking and before a longitudinal movement is imparted thereto.As the shank portion of the handle comes in contact with the inclinededges of the slot in the bearing D, an outer longitudinal movement willbe imparted to the bolt for the purpose of throwing the angled endthereof out from behind the keeper 0 and which will allow the door to beswung open.

By the provision of a latch made in accordance with my invention, itwill be noted that a simple and efficient means is accorded whereby thekeeper may be operated manually' in the manner disclosed, the lockingof'the door being'securely held in a locked relation when the handle isat its highest throw and the door released automatically when the handleis at the limit of its throw inits opposite direction.

A device made in accordance with my invention will afford means wherebya powerful leverage may be obtained and by which the door may beoperated readily regardless of the swelling or warping of the door andthe initial loosening of the door from a jammed position easilyaccomplished.

What I'claim to be new is 1. An eccentric latchfor doors, comprising acombination with a door and casing to which the same is hinged, abearingmember fastened to the casing and having an angled slot in its wall, arocking bolt mounted in said bearing and having an angledend .and-

a handle fixed to the bolt and extending through said slot, a keeperpivotally mount- I ed upon the door and having a beveled flange againstwhich said angled end is adapted to contact to tilt the keeper, aprojection upon said keeper against which said angled end of the boltcontacts to return weaves the keeper to its normal upright position, asset forth.

2. An eccentric latch for doors, comprismg a combination with a door andcasing to which the same is hinged, a bearing member fastened to thecasing and having an angled slot in its wall, a rockingbolt mounted insaid bearing and having an angled'end and a handle fixed to the bolt andextending through said slot, a-keeper pivotally mounted upon the doorand having a beveled flange on one edge thereof against which the end ofthe bolt is adapted to contact, causing the keeper to tilt, the upperportion of the latter having a slot therein, a pin pro- I jecting fromthe door and passing through said slot, and means for returning thekeeper to its normal position, as set forth.

3. An eccentric latch for doors, comprising a combination with adoor-and casing to which the same is hinged, a bearing member fastenedto the casing and having anangled slot in its .wall, a rocking boltmounted in said bearing and havingan angled end and a handle fixed tothe bolt and extending through said slot, a bail-shaped keeper pivotallyconnected at its lower end to .the door and having a beveled flange onone edge thereof against which the end of the bolt is adapted to contactand cause the keeper to tilt, said keeper having a lateral projectionand against which the angled, end of the bolt is adapted to contact tothrow the keeper to its normal upright position, as set forth.

In testimony whereof I hereunto afix my signature in the presence of twowitnesses. ANDREW J. ALLISON. Witnesses;
